For some reason when I use the objFile.ReadLine method to read my text file, the entire file is returned as one long line. The file I'm opening is using CR line endings instead of CRLF or LF line endings. Does anyone know how I can read this file line by line in vbscript if ReadLine does not recognize CR line endings? Code is below:

.ReadLine won't work in your case, because it depends on the existence of a vbLf character. If you don't want to re-encode the line breaks or read the entire file and split it at vbCr (if the file is not-so-large):

text = objFSO.OpenTextFile("C:\Path\To\My\File.csv").ReadAll

For Each line In Split(text, vbCr)

MsgBox line

Next

Re-encoding the file can be done like this:

Set fso = CreateObject("Scripting.FileSystemObject")

filename = "C:\path\to\your.csv"

Set infile = fso.OpenTextFile(filename)

Set outfile = fso.OpenTextFile(filename & ".tmp", 2)

Do Until infile.AtEndOfStream

c = infile.Read(1)

If c = vbCr Then

outfile.Write vbCrLf

Else

outfile.Write c

End If

Loop

infile.Close

outfile.Close

fso.DeleteFile filename, True

fso.MoveFile filename & ".tmp", filename

Or you could use something like recode for the conversion. Most text editors (e.g. Vim, Notepad++, SciTE, UltraEdit, …) can do this kind of conversion, too.
